Application filed. July 28, 1909. Serial No. 509,994.

To all whom it may concern:

Be it known that 1, DANIEL ANTHONY, a citizen of the United States, anda resident of Greenwich, in the county of Fairfield and State ofConnecticut, have invented a new and Improved Shutter or Fire-ShieldYVorker, ot which the following is a full, clear, and exact description.

This invention relates to certain improvements in workers for shuttersor fire shields, and more particularly to certain features otconstruction, whereby the worker may be used in connection with shuttersor tire screens on windows set deeply into the wall of the building.

My improved worker operates to swing the shutter or shield outwardlyfrom the window casing, so that it can lie against the reveal of thewall near the window opening.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specication, in which similar characters ot reference indicatecorresponding parts in all the iigures.

Figure 1 is a horizontal section and partia-1 plan indicating theconstruction and operation ot the device, this section being takenapproximately on the line 1 1 of Fig. 2; Fig. 2 is a vertical sectiontaken on the line 2-2 of Fig. 1 and passing through the upper part ofthe window easement to indicate the manner of supporting the shutter;Fig. 3 is a plan showing one of the worker arms in detail; Fig. t is avertical section through the worker arm shown in Fig. 3, this view beinga section on the line 1 4 of Fig. 3; Fig. 5 is a plan of a guide cleatwhich is attached to the shutter or tire shield and which connects withthe arm shown in Figs. 3 and l; Fig. 6 is a side elevation of the guidecleat; and Fig. 7 is a cross section on the line 7 7 of Fig. 3.

Referring more particularly to the parts, and especially to Figs. 1 and2, 1 represents the wall of a building near a window opening in which awindow easement 2 is set. The window easement may be provided withvertically sliding sashes 3, as shown, which may be supported in theusual manner by counterweights a moving up and down in the easement. Theouter side of the window is closed by a pair of shutters, such as theshutter 5 indicated in its open position and lying against the outerface or reveal 6 of the wall near the window opening.

l My improved shutter worker may be used in connection with any form otshutter or tire shield, which is used with a deeply set window, andwhich is capable to swinging outwardly against the outer surface of thewall at one side orn the window.

In the accompanying drawings, I have illustrated a form of worker inwhich the arm is extensible to tit shutters or shields set variousdistances back into the wall, and have also illustrated this form inconnection with my improved extensible hinges constituting thesubject-matter of my copending application, Serial No. 509,993, tiledJuly 28, 1909.

By making both the hinges and the arms extensible, the shutter may bemounted and operated irrespective of the depth to which the shutterswings inwardly beyond the outer surface of the wall of the building.These hinges 7 have main leaves 8 connected by pintles 9, and each hingehas a plurality ot threaded openings 10. The main leaves are mounted toslide in angle brackets 11, which latter have iianges 12, for engagingwith the edges of the leaves. The brackets 11 have webs 13 which engagewith the leaves, and in addition they have flanges 14: disposed at rightangles to the web and attached by suitable fastening devices 15 to theshutter. Diagonal braces 16 connect the webs and flanges 14:, andclamping screws 17 extend through slots 18 formed inthe webs and intothe openings 10. rIhe hinges constitute no portion of the presentinvention, and are illustrated in connection with my improved workeronly to bring out more clearly the advantage of' forming my worker armextensible.

At the inner extremity of the hinge the angle bracket is attached to ahanger seat 19 which is in the form or' a strip attached to the side ofthe window easement. In the upper part ot' this strip 19 a pocket 20 isformed in which there is mounted rotatably a worm 21, said worm beingarranged upon a horizontal axis. This worm is provided with a sprocketwheel 22, and a sprocket chain 9.3 passes over this sprocket wheel andpasses through the window easement to the interior, at which point thechain hangs down, as indicated in Fig. 2, so that it will be withinreach or" a person in the interior.

1` erases @n the outer side of the strip 19, a bracket 2l is mounted, onwhich there is mounted a worm wheel on a vertical shaft or pintlc 2G. Tothe lower end ot this pintle 2G an extension arin 2T is rigidly secured.The details ot this arm are shown in Figs. .f3 and rlfhe arm is 'formedot a body piece or main piece Q8 having a square socket 99 which isreceived on a square neck 3() formed on the lower end or the pintle orshaft 2G. The body piece 2S is of channel form so that it presentsAflanges 31 on its edges connected by a web The web is provided atsuitable points with threaded openings 33 which are adapted to receiveremovable clamping bolts 3l. rl`hese bolts are adapted to pass throughslots which are formed longitudinally in an extension piece 3G, as willbe readily understood.

lf provide tour of the threaded openings 83, and three slots, as shown.These threaded openings are arranged in pairs, and in Fig. iltheclamping bolts are represented as placed in the outermost pair. Theextension arm 3G in this view is shown in its midpcsition with respectto this adjustment oi. the clamping bolts Sie. rthe slots 35 willevidently permit the ezrtension arm to be adjusted. out tarther untilthe inner ends et the slots come against the clamping bolts, or theextension arm may be adjusted inwardly in an opposite direction. ltdesired, the bolts 3st may be moved into the innermost pair oi openings,when similar adjustments ot the Xtension arrn may be had. The outer endot the extension arni or bar 36 is provided with a pin 3T having aroller 3 which .is received in a slot 3f) which extends longitudinallyin a guide cleat rett). rihis guide cleat is attached to the t'ace ofthe shutter which is disposed adjacent to the wall when the shutter isopen, as indicated in Fig. 1. rlhe guide cleat is attached in ahorizontal position by means oit a flange all which extends throughoutits entire length. At the end of the guide cleat which is adjacenttothe. hinge, the cleat is formed with a laterally projecting neck d2, andthe slot 89 runs out into this neck, as shown. Art the point where theslot 39 runs out into the neck it terms a gradual curve or arc 43 whichguides the roller into the neck, as will be readily understood.

lil/lith the shutter in the open position shown in Fig. 1, it will beevident that it the chain is pulled in the proper direction the worm 21will rotate in such a way as to rotate the wheel 25. The shaft ot' thewheel 25 being rigid with the arm Q7 will tend to swing the arm 9,7inwardly. 1n this way the arm will be made to exert a pull upon theshutter tending to swing it in toward the window. 1n this way the hingeswhich support the shutter will be flexed and the shutter can then befurther swung inwardly until it closes the window, as indicated by thedotted lines in Fig. 1. @n account ot the slots 35 ot the extension barotl the arm the arm can be adjusted so as to suit the particularbuilding to which it is applied, that is, it' the wall is unusuallythick 'the extension arm can be further extended, and vice versa.

rThe laterally projecting neck l2 is very important, for if it were notpresent the roller 3S could not operate eli'ectively to open theshutter, for in its outward swinging movement in opening the shutter theroller would tend to slide out in the slot and would simply becomejammed. With the laterally. projecting neck, however, the slot presentsan edge disposed substantially at right angles to the plane ot theshutter, and against this edge the roller exerts its opening torce.

daving thus described my invention, 1 claim as new and desire to secureby Letters l)atent,-
